DNA Replication Has Been Filmed for the First Time ucdavis.edu

I can feel there is something really interesting here but the writing, title and explanation here seems to be poor. The surprise here is the random starts and stops as well as 10X speed difference in the DNA replication process. Wouldn't it be more surprising that these processes run at the same speed?

"...started watching individual DNA strands..." I'm wondering how important the visualization and nature of "filming" helped to form the idea or prove the hypothesis that replication is a async process. I didn't quite gather which is more impressive, the filming or the discovery.

Sometimes the traffic in the next lane is moving faster and passing you, and then you pass it. But if you travel far enough you get to the same place at the same time. also doesn't quite make sense to me as the video clearly shows no queuing structure as seen in real life traffic, and there is no real hypothesis to explain the sudden stops and starts.

> Its a real paradigm shift, and undermines a great deal of whats in the textbooks, he said.

Sorry, but is this really that new? I've never been taught that the DNA strands coordinate with each other while replicating, so it seems quite possible that synthesis of each strand can be independent of each other.

I'm really not sure the drive for garbage collected languages in memory constrained systems with no user recoverability. Seems like a recipe for a device that just stops working from time to time.

Embedded systems, IMO, must be deterministic, reliable and consistent. Introducing garbage collection violates these three principals. Without them, how can you guarantee an interrupt can be reliably serviced in time? How can you guarantee that memory growth won't be exhausted because of some unexpected condition which prevents a timely GC? Many embedded systems developers don't even use malloc() in lieu of static allocations so they can actually understand their memory requirements.

It's either big enough for Linux, in which case have at it, or you need to reconsider why you're down in the kilobytes of total memory with a garbage collector.

This is true even at a personal level. If you think you know why you act the way you do but you have never done an experiment to validate it you have a pretty good chance of being wrong. Even for simple things, like how fast you drive, is it the speedometer and you are looking at it, or is it how your engine sounds, and if turn up your music do you drive faster and is that because you are more aroused/excited, or is it because you can't actually hear how loud your engine is? Or maybe it is something else entirely.

> there is no homunculus (or soul, or separate entity) calling the shots for you, but even if there were a mini-me inside of you making choices, that mini-me would need a mini-mini-me inside of it, ad infinitum.

I find it kind of amusing that people think free will is an illusion. It's a great illustration of how you can get people to believe anything, including things that violate their most fundamental perceptions.

This "Science disproves free will" thing has the epistemological hierarchy reversed: one of the surest things I know is my own will. Before Descartes could proclaim "I think, therefore I am" he had to choose to make that proclamation.

The argument that free will can't exist because it involves infinite regress is not particularly convincing: if anything, we should expect that our agency springs from something as bizarre as a causal singularity. Consciousness is weird as hell, and I expect the true nature of consciousness will turn out to be weirder than we can imagine.

The schism between our science and politics is finally getting airtime. Liberal western politics are based on individual liberty and free will. However, mainstream science maintains that we're neither individuals nor have free will. Do we try to reconcile both views? Or do we drop one in favor of the other?

This, by the way, is also the subject of Homo Deus: A Brief History of Tomorrow, by the same author behind Sapiens.

Really? Really now? Thousands of years of slavery, war, discrimination, class struggle, superstition, genocide, and at least a few centuries having to wear really stuffy clothes in the summer, and six years of war was the worst thing that happened? I didn't read the book, but this is a farcical idea that requires aggressively downplaying all of both the atrocity and perpetual minor trauma of recorded history.

The worst thing humanity ever did to itself was religion, but second to that was politics, so WWII can take the silver medal. Ironically, the best thing humanity ever did to itself was war, as it necessitated the development of technology to maintain hegemonic dominance.

Call it anyway you want, lizard brain, flyers (Castaneda), Yaldabaoth (agnostics), this force that pushes evolution on earth at great speed through predatorial behavior like competition and flight or fight.

We humans are the most intelligent species and still can't overcome it, as a civilization whatever political system or religion we tried no matter how hard we try we can't seem to overcome it, we still have wars and violence.

When few succeed to inspire people to overcome it and fight without violence like Mahatma Gandhi did they inspire humanity and are called saints by their nation.

When an individual can control his own feelings to such an extent that violence or anger feelings can no longer touch him we call him enlightened.

Maybe this force is not only trying to help us evolve but wants to teach us something marvelous if we overcome it.

I'm calling it, Intel is going to be a shadow of it's former self in 5 years. They have had tremendous issues competing in almost anything outside of x86 processors over their entire lifespan. They consistently get outmanuevered in gpus, ssds, low power socs, machine learning, et cetera. The x86 platform that they currently own, is mostly due to intertia and fab facility advantages.

AMD, was able to launch a pretty competitive CPU despite massive delays because Intel has barely improved the ipc of their processors over the last 5 years.

Meanwhile Apple is betting on iPads being the future computer of the Everyman and they make their own chips. Microsoft recently acknowledged that windows basically has to run on arm for the future proofing of their platform. I guarantee you start seeing more arm based windows computers soon.

Intel recently told everyone they're willing to sue for patent money, the last desperate act.

Intel better have a leapfrog cpu in the pipeline or it's over.

FYI, as someone who worked with the Edison I can't say I'm surprised. Flashing the Edison was nearly impossible and a big pain. The hardware routinely crashed. Much of the low power "specs" came from (overly) aggressive power management which introduced momentary delays and pauses. I'm happy to see them go and never want to work on such a platform again. The GPIO stopped working reliably at higher speeds despite their spec claims.

By contrast, the raspberry pis and even the Ci20 are significantly more stable and easier to work with. Their specs far more truthful.

Long overdue. I had hope that Galileo might be an Arduino/Raspberry Pi competitor, but Joule was blatantly an attempt to recoup some of the cost of their already-cancelled smartphone SoC program.

Why did Edison fail:

 - it was too expensive compared to other BLE and WiFi capable SoCs or combinations of chips. - x86 compatibility doesn't matter. - power draw (~1W) is too high for the places where one would want to use this SoC. - the Yocto -based SDK was a mess. Every feature had a caveat and it was a pain to build. - there was never a clear commitment from Intel that they would make these in bulk for manufacturing.
The new hotness are the Espressif (ESP32) and MediaTek (mt7697) SoCs.

 - low power draw (~300mW), even lower at sleep (50mA - nA depending on what kind of sleep), - SDK is FreeRTOS based, - the "MCU features" like GPIO, PWM, etc, actually work all the time.

This is unsurprising. My experience with the Edison: Cool little product with a lot of potential, but the stability problems, lack of timely releases of updates, lack of support for common libraries in their package management system, etc. were all bad signs. I never got the feeling that it would be safe to build a product around the Edison.

Ah and I am so lucky I never switched to Galileo while I was tempted during its release. For some reason I thought it wouldn't work out. Something felt off for some reason and I could kind of get by with Raspberry Pi.

Reading hackaday comments it's probably from the documentation and Intel's doing, not for the technology on itself. I am guessing that open source OR community > closed source or company (as in Raspberry Pi with a great community vs Galileo or Arduino vs anything else) for these kind of things.

It's not like Intel hasn't tried new things over the years, before becoming a huge ARM CPU vendor (XScale) they had the i960 MCU, which was pretty good and the failed i860 VLIW, which was super-promising for graphics and image processing but the compilers never delivered.

It's just that the x86 was always so huge that all the other projects never got traction.

I worked on a handful of products using Edison, and was speaking to Intel less than a month ago about their Joule line at a conference, where they assured me Joule was the future.

All of these chipsets had (and still have) huge promise, but have been mired in really puzzling and terrible board design issues.

You can tell that there are two different groups at Intel, the "Core" and the "Iot".

The Edison was super powerful, price competitive, and an honestly wonderful platform to dev on. YOCTO, while a weird decision, was a pretty vanilla Linux flavor and easy to pick up.

With all that promise though, the botched the silicon. The 2nd cpu on Edison, the Quark 100mhz one, never actually worked. They were shutoff in firmware from day 1 because of presumed hardware issues.

Even worse (and the reason we stopped using Edison), the SPI bus had so much electrical crosstalk on it from not being properly routed or shielded, you couldn't use it at anything over 25hz with a SINGLE bus endpoint. This removed 90% of the real-world uses for the Edison to drive displays, sensor and motor arrayset al. Intel knew it was a problem and consciously decided not to Rev the board to fix it.

Gallileo and Joule are both underpowered and incredibly overpriced devices. Today, the raspberry pi 3 is the hobby standard, and in nearly every real world use case, it is orders of magnitude more performant at 10% or less of the cost.

Intel IS is trouble, because this is their third botched attempt to enter the world of embedded computing and mobile computing.

First was the Atom, which isn't bad, but is too power constrained to compete with ARM. They made some good efforts here, but the cost is higher and perf/watt significantly lower than ARM.

Second was their foray into mobile, trying to branch from Atom. Anyone here ever use an Intel powered phone? Well they spent billions on it, never to have a mass market device actually appear. Same problems - while have equivalent performance to ARM, prices were 30-50% higher and performance per watt was significantly worse.

Now here we are with attempt 3. With the same issues. Intel fundamentally doesnt know how to design, manufacture or sell embedded chips.

It's a completely different market motion, different customers, different constraints, shorter cycles and much much different competitive landscape.

AMD isn't going to "beat" Intel. They have fundamentally the same problems. Both AMD and Intel aren't going to go bankrupt, but they are going to continue the slide into much smaller scale manufacture.

They are both being eaten by the dozens of ARM vendors, by the FPGA movement, and by public cloud data centers. It's a reduction by a thousand cuts, making it that much more difficult to do anything about it.

One thing to keep in mind is that in 1997, HK's GDP was about one sixth of China's (even though China has 200x the people), and it was a very important conduit between China and the world: In the early 2000s, HK's port had about as much volume as Shanghai and Shenzhen together.

Today, HK's GDP is barely 3% of China's, and the ports of Shanghai and Shenzhen together have 3x the throughput of HK. (Just have a look at these pictures: http://www.dailymail.co.uk/news/article-2478975/Shanghai-por... )

In other words, HK used to be hugely important for China. Now, it isn't, and with rising Chinese nationalism, HK is being seen more and more like an unruly and spoiled child.

The grievances of HK's population are real: a political and business establishment dominated by property tycoons (and increasingly mainland Chinese political factions) keen on maintaining their privileged position; huge economic inequality; a slow erosion of political liberties ("salami tactic").

That all, of course, gave rise to the Umbrella Movement in 2014.

However, given that the Chinese Communist Party is not inclined to weaken its grip on power, and extremely protective of the (perceived) territorial integrity of China, I don't really see how this will end well. :-/ Here's hoping.

This is very different from what I was told by certain exasperated civil servants at the time in Honkers which was that initially China didn't really want change at all as they thought any more of this democracy and capitalism poison (not to mention triad crime) needed to be contained and certainly not brought into China proper and that they would have gladly ignored the expiration of the lease but for the idiocy of the Brits insisting on some sort of replacement framework. They'd have gladly just carried on taking the money pretending it didn't exist. Deng had to come up with a fudge - one country, two systems and Macao followed suit thereafter. But it was a long time ago and that may have just been Lily Wong.

edit: for example the chinese did nothing to stem the tide of people to-ing and fro-ing when HK was still a colony, I recall some squaddies complaining bitterly about having to shoot at them up the hillside whilst People's Army looked on bemused.

For those who don't follow this, in many ways this experiment has, in my view, shown signs of failure.

China also almost surely has arrested/kidnapped Hong Kong citizens (authors) in Hong Kong who push for democracy.

Beijing is seen to have an increasing amount of political influence on Hong Kong. Hong Kong does not have the independence to create a democratic system.

Hong Kong people don't feel like they can control much... so most just go about their day to day lives. They don't like Beijing's power, but what can they do? This is not the way the British agreement was set out ("One country two systems"). Unfortunate, but probably predictable.

typical biased article from CNN.

when talking about the handover, the article claims that

"The people of Hong Kong were not party to the discussions, nor were they consulted about the final decision, which had a profound effect on their futures and freedoms."

Did the people of Hong Kong party to the "discussions" when UK took Hong Kong after the Opium War? Were they consulted about the final decision, which had a profound effect on their futures and freedoms?

It also need to be highlighted the term Opium War - British fought a war with China so they could sell opium to a nation, they got HK as a bonus for such Opium business. Next time when you see thugs in your local undesirable neighbourhood dealing drugs, think about the British government because they were the same - I mean actually worse, when was the last time you saw drug dealing thugs directly took people's land/homes after selling them drugs?

Before anyone jumping up and down arguing that it was more free under UK - was polygamy legal in Hong Kong until 1971? Maybe you want to discuss with women in Hong Kong and lecture them why there were more free under British Hong Kong.

I feel like the article definitely has some merit but the timing of it (days before a TBD announcement on token trading), the inclusion of very obvious non-unique points (i.e. not scalable, anything Bancor can do Ethereum can do - uh, why not include the definition of Turing complete here) and the false assumption that Bancor's use case is for a groundbreaking ERC20 token that's going to be traded on every exchange makes the author's claim dubious.

A more likely use case for Bancor is some SMB (store/restaurant) or content creator issuing tokens to be used for membership reward/points or for voting on a new video/project idea, not for Augur/Steem/Gnosis 2.0 to issue an ICO.

If you take this gross assumption of the equation, his whole argument about slippage or "trailing the market", etc are gone. You're issuing some small time tokens. There no reason to always buy back from the market and there are no big players trying to "deplete your reserve." The author makes it sound like I'm selling some popular cryptocurrency at a fixed price and am being left to bleed dry when in actuality, I'm issuing my_random_token for friends and customers.

I didn't review the code but if what he's saying is correct, there is a reason for alarm regarding their reimplementation of basic arithmetic functions(!!!) and user overpaying.

By trying to make this into a laundry list, it comes more off as a FUD argument, very similar to what Bitcoin maximalists were doing post the DAO hack to Ethereum.

The underlying problem here is that the ICO model as most-frequently implemented is pretty broken.

It's kind of a like a hybrid between an IPO and a Kickstarter, but:

1. With kickstarter, the reward has roughly constant value with respect to the total funds raised;

2. With an IPO, the supply is predetermined. While the cost per share may be astronomical by the time you get around to buying in, it's clear what fraction of the offering you're purchasing.

ICOs tokens typically have:

1. value inversely proportional to the total funds raised; and

2. (since supply is not determined until the end of the ICO in many cases) no clarity around what fraction of the offering an investment actually purchases until the offering is complete.

This leads to some pretty crazy situations, Bancor being the most recent and most notable example, but in general, it just doesn't really lead to very sane practices.


This is precisely why IPOs are conducted the way they are, with investment banks pre-purchasing a predetermined number of shares just shy of what they expect to be a fair market value, handing that money to the company, and then selling those shares on the open market.

Thanks for sharing this. I did a deep dive into Rust when I was tasked with implementing an interpreter[0] for school, and found the language to be very enjoyable to work in. While I have tried to convince other friends to try it, they still object citing a steep learning curve and the thought that it will never replace C++ or Java in mainstream development ecosystems. It is resources like these that will help lower that barrier to productivity. :)

I do wonder whether sometimes the code here is using trendy tools just to be trendy, though. For example, is

 const getDistance = (state, rotate) => ["x", "y"].reduce((object, axis) => { object[axis] = Math.abs(state[axis] + rotate[axis]); return object; }, {});
really an improvement on grandpa's version

 function getDistance(state, rotate) { return { x: Math.abs(state.x + rotate.x), y: Math.abs(state.y + rotate.y) }; }?

I still remember the day I read the article on the Mandelbrot set and went, "Whoa, I understand the math!"

I went on to write my first Mandelbrot renderer in Python. I was delighted, in a way, that it worked, but badly disappointed at the performance.

I rewrote the thing in C, and then rewrote it again to make use of multiple CPU cores. I am certain there are Mandelbrot renderers out there that put mine to shame. But still, it was fun, and I got some pretty desktop wallpapers out of it. And I learned a thing or two along the way. Also, I rewrote it again using PVM (Parallel Virtual Machine) to spread the work out across several computers. So I actually learned two or three things along the way. ;-)

In a previous job, I had a supervisor who learned programming in the mid-80s who told me about rendering the Mandelbrot set, then using bit-twiddling on the VGA memory to change the color palette on the display. I was not sure if I should be envious to have missed those times or happy.

It's amazing how unpleasant most media sites are to read. Medium may still be better than most, but, like Gruber points out, they've been heading down a bad "growth hacking" path lately.

What really blows my mind is how awful so many websites from old publications with high-quality print editions are. A lot of these publications had quality standards for advertisers, and they worked hard to design nice-looking print layouts. As a result, even if there were a lot of ads they were at least unobtrusive and often kind of interesting and worth looking at in and of themselves. But it's like publishers are somehow incapable of thinking about a website the same way they think about a magazine.

When I end up on a website that takes fifteen seconds to load, makes text jump around as different ads are displayed and hidden, autoplays video, and pesters me with popups I wonder if anyone who works at the publisher ever actually uses their website. I mean, who, in their right mind, could ever think they were providing an even halfway decent product?

I have absolutely no sympathy when legacy publishers who peddle terrible, low-quality product struggle and go out of business. I mean, I hate to see media power consolidating into Facebook's hands, and it sucks when people lose their jobs, but these publishers have no one to blame but themselves.

Python: interactive glue language between high performance C libraries. It's funny how we have converged on this solution, I use it daily so I'm really not complaining but I really didn't see this as one of the logical outcomes of the various programming language streams.

But when you think about it it is kind of logical: inner loops and low level code tend to be fairly static and are often re-used so it pays of to write them in a language that maximizes for that use-case, but structure can be executed much slower and re-use is relatively low when going from one application to the next so it pays of to write that in another language.

So we get this split roughly halfway down the application stack where we switch from interactive and interpreted high level language to compiled low level language.

It's a very interesting optimum.

This is a great story. But...someone who has the intelligence and work ethic to do this probably wasn't going to be homeless for long.

Honestly, there are probably millions of people who pull themselves together like this - it's just they end up working regular jobs like maintenance work or burger flipping that aren't as inspirational.

The problem with stories like this is they conflate two problems:(1) being down on your luck (but hard-working and reasonably intelligent)(2) being stuck in a poverty loop due to mental illness, criminal record, or countless other complex factors.

Problem (1) is something a lot of HN readers can relate to, especially in their early twenties. Hence, the popularity of this article.

Problem (2) however is the much bigger problem. Unfortunately, what this guy did is only marginally useful in coming up with solutions to that problem.

This seems incredibly pricey, especially for the services you seem to be promising (which, for all the airports I spot-checked, amounted to Meet and Greet, Custom Assistance, and Transport Assistance). Fast tracking was not covered in the base price for any of the airports I checked. Connecting flight service is $745 per person!!!

Your example pricing was for 2 people, but I checked and it looks like the price for 1 is the sameSFO is $375 (for both 1 and 2 passengers), likewise for BOM ($340 for 1). Given how much you are pushing the business traveler angle, I think it'll be more honest to talk about price per passenger, as business travelers rarely travel in pairs.

Business travelers typically travel light, and might not need as much baggage assistance or custom assistance. Likewise, you only claim to provide assistance booking transportation (the passenger pays for the actual transport), which means that unless someone is traveling to a very very 'foreign' land (where no one speaks English, the signage is very confusing, you are very likely to be cheated, etc. etc.) I don't see too much value coming out of the service for most travelers.

I understand it's a discretionary spend, and that you can charge whatever you want, and that three or four hundred bucks is throwaway money for many business travelers (or their companies) but I was personally quite disappointed to see the pricing, because I was hoping to use it to get, say, an aging parent through all the airport hassle. For 50-100 bucks, worth considering. For 400, not so much.

Hey Blaine! Congrats on your launch.

My co-founder Sarah and I just moved from SF to travel the world while we bootstrap our startup, Canny. I'm also a huge fan of products like Shyp, Instacart, Prime Now, and Gobble that let you trade money for time. I think I could be your target customer.

However, $210 sounds pretty darn expensive for HK. I just went there last Nov. It didn't take much research at all to figure out how to get the 2 of us downtown on the bus for $40-50. The immigration process was smooth.

Maybe I haven't felt the pain point you describe, or maybe I'm not wealthy/spendy enough to be your target customer.

My feedback for you would be to work on crafting a story that sounds like "oh man, that's a life saver" rather than "save a few hours". Or maybe be more obvious that your product is just for the very wealthy and business travelers - like a high end credit card or something?

Just my 2 cents, hope it was useful. Best of luck!

pdovy 5 hours ago 1 reply      
I'd agree with other commenters here that it seems pretty expensive for what you're getting, or at least the value proposition is poorly presented. For example, I don't see any reason why I'd want to pay for this at a US airport (at least from the perspective of a US citizen). On the other hand if you told me the immigration line at XYZ airport was typically 45-60 minutes long and you could guarantee me priority access, there is a value there that I might pay for.

The pricing also seem really opaque - the prices even within a single country vary (from $250 at JFK in the US to $375 at SFO, why?). Certainly the going rate for a fixer at the location must play into this, but from a customer perspective I'd expect the fee to mostly depend on the value to me - I'll pay more if the expected level of delay or hassle is high. That might actually be inverse of the rate you pay the fixer - there's less value in US/Europe for me than if I'm traveling in e.g., Southeast Asia.

Overall though I think this is an interesting idea and I'd be a customer at the right price point, at least for certain destinations. Good luck!

It's a good idea, and it reminds me of "handlers" in the general/business aviation world. When you land, they expedite your fueling, customs, immigration, overfly permits, flight planning & routing, and more.

Back to normal travelers - I wish there were a free wiki that covered all this, since it seems like it's just a matter of having the right information. Like knowing which office to go in, what forms to have ready, etc. I guess it'd be more targeted towards casual travelers who won't pay $200 for this kind of service.

Do it guys! There is definitely a demand for this!!!

VIP lounges, fast track and other premium services are all different from airport to airport, procedure for ordering them is unpredictable and sometimes cumbersome (like, faxing a request on the company blank and paying through the wire transfer ONLY, no credit cards accepted - that isn't an exception, but more like the accepted practice). If you will figure it out to the Uber level, when i can take an iPhone app, type in my booking reference for the flight, pay through the attached paypal account or CC, predictable and reasonable price, and someone will meet me at the entrance to the airport or off the plane and get through everything - that will be a killer!

First of all this is a great service, and congratulations on the launch.


After checking I am a bit disappointed:

- Istanbul: $235.00 Not including "Fast Track Immigration/Customs" for 2 passengersyou can get local fast track card (I think it is around $500 for a year) which grants fast track on immigration/customs and also for all security checkpoints for 2 pax

- Amsterdam: $345.00 Includes fast track vs Privium Basic 121 yearly incl. VAT

- London: $220.00 Includes fast track vs AFAIK it is around 50 GBP for fast track for one time

Also I think if target is business travelers, a lot of airlines provide complimentary fast track for business class travelers. I don't recall not using fast track when flying business.

TBH I dont think Meet and Assist has big value, unless you provide some added value there.

Also at least I was expecting some lounge access on departures.

How does this work, inbound, to the US ?

When I return to the US (San Francisco) on first class or business tickets there is no segregation of lines/service - you queue up in the big line and wait your turn (45-60 minutes later) like everyone else.

Other than diplomats, I see no mechanism for expediting immigration/customs inbound to the US and my (short, reckless) research suggested that expedited immigration/customs is not a perk for any level of ticket price or "elite" status.

Perhaps I misunderstand ?

I landed in Beijing Sunday and arranged a car from my hotel since Uber doesn't work here. I arranged via email for the Intercontinental to send an Audi for me and my colleague for CNY 780 (USD 114). Included in the price was an expediter service of a very nice woman who met us at the gate and accompanied us through immigration until she put us in the car.

In Europe, your service doesn't make sense either, because Uber to a hotel is so convenient and reliable.

I'm your target audience, but I don't think you've hit product market fit yet.

In Denpasar, Indonesia (the airport for Bali), you could always get through immigration/customs by bribing the immigration officers. Actually, they would come through the lines telling us about their "service" given that they immigration lines were moving so slowly (and I have a feeling, this was by design). With the new airport and more efficient immigration lines, these people have disappeared, however.

I wonder what kind of relationship you need to set up a kind of service that would even allow you to meetup at the arrival gate? Many airports simply have nothing for this beyond VIPs, I can't think of any airport in China that would do this, for example, which is why all the people are holding up signs waiting for their charges outside of customs.

Edit: they seem to offer service at PEK (https://www.solve.com/pricing/pek), but DAMN those prices are sky high (start at $1,690). I guess that answers my question then.

Hopefully you will have better optimization of providers in the future, allowing for better pricing.

For instance, arriving at SVO (Sheremetevo airport in Russia) you want $735 for meet and greet and transportation help.

Yet local pricing for transportation into Moscow is no more than $75 for the one way trip (SVO is a bit outside of Moscow proper) and, well, very capable translators are available for what, $50/hour or less? I've paid as little as $10/hour, though not at the airport.

SVO already has express lanes IIRC for USA citizens at least. You should either have this info noted or possibly figure out how to integrate this into your service.

I do a lot of international business travel, mostly in business. 3 figures of flights last year. I would use this service, but you're about 2x as expensive as I'd pay for it.

For example, you want 140 for landing at Suvarnabhumi. This gets me Fast Track immigration, but I already get that if I'm landing in business, and help with onwards transportation, but as per most airports, the place is swamped with good quality limo transfers for maybe 2x the price of a regular taxi. So I'd be paying 140 for a cart from deplane to immigration, plus perhaps shortening priority immigration, and help with luggage. That definitely has some value, maybe up to 70, but 140 is way too much.

Like the idea! Especially on airports that are famous for their lines and waiting time (JFK...) winning time at immigration and avoid standing in line for a taxi quickly saves you 2 hours. For the business traveler that is almost 2 extra meetings, and for the family traveler that is 2 hours less stress and crying children.

I registered a domain name a while back 'DeliveryOnArrival.com' with the idea to also accelerate business travel. The plan was that you could travel with less stuff (and therefore could bring only hand luggage) and get what normally use and need delivered on arrival: at the airport gate, in your Uber, in your Hertz rental, or at your hotel. Never executed on it though, maybe a nice add-on service (I would use it).

I've been dreaming of a service like this since last year. Im travelling to Malaysia in a couple of weeks from Heathrow and would love to get through security faster. I paid $8 (approx) to get through security faster at Luton airport when i was travelling to Amsterdam and i loved it. But unfortunately such a service is not available at Heathrow unless i buy business class or have an executive club membership.

$225 is rather pricey for me. Its a bit beyond my budget, but id happily pay $60ish to get through security/customs faster on my out to Malaysia from Heathrow if it was possible in anyway. If anyone from Solve is reading this please let me know if you can do something for me?

I think this can make sense. I recently traveled with a toddler for the first time.

At the same time, in the US they didn't send me to any special line and was horrible. I would have easily paid 200$ to avoid staying in line with a toddler.

The website though seems so vague. It is really hard to understand exactly what I would be paying for. There is a little bit of everything and nothing is very concrete.

Interesting approach to getting at some dark spaces in our current understanding. What kind of computation time does it take to run against a single amnio acid chain? Can you get much (nice disorder predictions?) out of an amino acid sequence alone?

Our protein design work has its origins coming from a different angle. But there are some interesting thoughts we've had about utilizing (well, dreamed up) technologies like yours to quickly make up a lot of ground between structural prediction, and empirical functional design.

Nice work lowering the entry barrier for machine learning in this space, which appears to be the aim of your company, but it's a bit of a tease to claim your data representation is great for supporting ML and stop short of doing any of that in the manuscript. I take it that's the next step?

On that note, is there any reason why the propensity classes alpha/beta/coil are still so widely used? Especially coil/turn/"other". It seems to me that these are ancient artifacts of structural biology that could definitely restrict human understanding of protein dynamics. Perhaps there is nuance in the chemical shift data that may help the design of better structural classes using ML.

Speaking as a guy with a lot of experience with voter data ( I built the first "where do I vote" apps for Google and helped found the voting information project):

This is actually almost entirely public data. Yes, including addresses and phone numbers and political affiliation. There are some states that is not public as part of the voter file, but you can still get it other ways publicly. For example: USPS, etc. Some states/players would make you sign agreements not to use it for commercial purposes.

The modeling info included is not public.

Acquiring 50 state data can be a bit of a pain, but there are at least two major players that will sell it to you.(I remember one of them literally laughed when I told them we would want the databases without any personal info included, because we just wanted the address to various political precinct mapping.)

Microtargeting is trying to unravel your political DNA, [Gage] said. The more information I have about you, the better. The more information [Gage] has, the better he can group people into "target clusters" with names such as Flag and Family Republicans or Tax and Terrorism Moderates. Once a person is defined, finding the right message from the campaign becomes fairly simple.

Neal Stephenson wrote a book called Interface which predicted a form of tech-enabled micro-targeted politics over 20 years ago. It was disturbing at the time; it's almost considered business-as-usual now.

I believe American democracy would benefit from including the study of such techniques in our educational curriculum. When I was in school, we studied advertising techniques to help us be skeptical. We need the same for targeted political messages now.

The real danger of data like this, in my opinion, illegal usage for voter fraud.

Find people who are likely to vote against you and likely to have poor voter registration documents, and remove them from the polls so they can't vote.

Find people who aren't likely to vote at all and vote on their behalf. In-person, the only verification required is name & address. By mail, the only requirement is a signature, which can be obtained from receipts (I assume this is available on black hat markets).

Leaving this S3 bucket as public-read allows for deniable coordination with illegal actors. I can't imagine they did this on purpose but that could be an explanation.

I have this theory that the only way regular people will start caring about privacy breaches such as this one is to use that data against them in a malicious way. Tell the average Joe that the data of all US voters has been leaked, "Hmmm. That's bad." and they move on with their lives as if nothing happened. Instead, if this data is used to impersonate the average Joe on social media or if it's used to trick their mobile carrier into porting out their number, then they'll take notice. (I am not suggesting people do this, it was just part of a thought experiment)

Unless the company involved is sued to bankruptcy and the people involved are prosecuted, sending a strong message to companies dealing with user data, nothing will change. But that's unlikely to happen as this company is backed by the RNC.

While we're on the topic of collecting personal data of people, there's a simple solution : just don't collect it unless it's absolutely necessary. Stop asking me to broadcast my address in my newsletter. Stop asking me to submit my billing address when I make payments online. Stop asking me for my mobile number when I visit a fast food restaurant. Most of the companies that collect this data are not competent enough to keep it secure. The reason companies ask for an address to broadcast in users' newsletters is some anti-spam act which does not prevent the spammers from doing their job. I imagine it's also a requirement for companies to collect a billing address for certain types of online payments. Change the law to remove these poorly thought out legislature.

More generally, we need regulations on how user data is used by companies. They should not be allowed to store user data indefinitely. If a user closes an account with a company, retain the data for a short period (eg- 1 year) and then delete the data automatically. Companies should not be allowed to build shadow profiles of users.

It would be good to see him make this a clear case of responsibility. Also, someone on the RNC side needs to get fired, too. I'm not sure who, but errors this big demand it.

This resonated well with me. I've always preferred email to chat, for many of the reasons cited in the article.

The trouble is, it's too far to the right. Some people don't respond for days. So we have tools with instant response expectations, and ones with variable expectations. Nothing with clear "within a day" expectations. Email used to be that way, until too many peed in that pool.

As an Amsterdam resident: What a romantic characterization of our high crime rates! Yes, the reason I still ride a shitty old beater of a bike is definitely my long lasting love for that piece of shit, it's not because I know that if I buy anything fancy I'm going to have to never take my eyes off of it, least it be stolen in under half a minute in certain parts of town[1].

Just came back from a week in Netherlands and stayed in Amsterdam. What a cool place to hang out and take in the sights. Cycling there is huge indeed. The big difference I noticed from Canada was the dedicated infrastructure they have in place. Dedicated cycling lanes everywhere, it's a proper form of transportation. As a tourist, this was weird, I nearly got mowed down a few times but because I was in the wrong and not paying attention. You quickly adapt and realize bike lanes are just as important to watch out for as vehicle lanes. The people are very friendly and nearly all speak English without issue.

I don't agree with cycling on the roads and highways here in Canada, it's chaos and frankly, dangerous. I don't really see if implementing what they have because it's already built in.

The thing that really jumped out at me was when I was waiting for a bus around zaanse schans, about an hour outside of Amsterdam in the country, there was an elementary school that just finished up for the day and every single student came out on bicycles. Myself and a group of Canadian's couldn't believe it. They all happily were socializing on their bikes tightly packed together while riding on the bike path in the country to their homes. Here in Canada nearly everyone takes a giant yellow school bus.

Very nice place, highly recommend checking it out if you have chance. Aside, saw the outside of the Atlassian Amsterdam office too ;)

One thing the article doesn't mention is how long the bicycle trips are. Surely the relative compactness of their cities are a major contributing factor!

I live in America and commute on my bicycle almost every day. For me the biggest obstacle isn't the hills (which there are plenty of) or even sharing the road with cars (which is admittedly extremely unpleasant) but the fact that in the quasi-suburban area in which I live, everything's so damned spread out that bicycling is very impractical.

mmjaa 9 hours ago 1 reply      
I've always enjoyed my cycling trips when I've been in the Netherlands - its just so calming and relaxing, and good for me - but without much stress. There aren't many hills, its for the most part very safe and bicyclists have a place in the transit system that feels very comfortable and, indeed 'right'. There really is something quite right about the feeling - you are getting fit, and going somewhere, and .. well, its just so easy to ride around.

After a month in the Netherlands, I always feel like going back to a car-based society is a huge step backwards. Like, there is a wall of concrete and asphalt and metal and fumes and busy-ness, and we're all just so trapped in it. Like prisoners.

I had watched about a million Dutch cycling videos before I went to the Netherlands, but it's even better than the videos make it out. Cycling in the Netherlands is safe, easy, and fun. I rode around with a four-year-old and an almost-two-year-old in a cargo bike and not for a second felt any stress or fear (and my kids absolutely loved it as well, fresh air and no carseats). I can't go half a mile in Seattle without worrying about getting run over. I basically gave up on cycling in America because I can't handle the adrenaline hangover anymore.

One more thing, as great as cycling is in Amsterdam, from what I can tell, it might be the least best place to cycle in the Netherlands, so if you only cycle in Amsterdam you're not even getting the best experience.

Why wouldn't it be?

It's faster than the tram; a bike is cheap and cycling is free; its way easier to park than a car; its healthy; there are cycle paths everywhere (inside and between cities); and everyone else does it, so you usually have company.

Southeast Asia is heavy on bikes, and used to be more so than now, and they didn't have infrastructure or culture --it was need. Japan is heavy into bikes too, and there aren't dedicated lanes, not that I'd object, but it's not necessary to make it popular.

The one thing in Japan, where accidents aren't as regular as in southeast Asia, is that both bikes and cars obey traffic signals --I think that helps a lot. Also many, many streets ate narrow, so everyone slows down, and aside from bosozuku, you don't have people going 40km/h down streets.

The nice thing about having many cyclists is that there's a high demand for cycle parking spaces which means you can run a good business guiding cyclists to available space. This is what we do at LumiGuide. See: https://bicycledutch.wordpress.com/2015/06/09/bicycle-parkin...

I'm Dutch, but think we tend to underestimate the impact of the flatness of our country, and the size of other countries especially the States. I've cycled on my normal 7-gear bicycle (and that might be considered fancy) from Newcastle to Carlisle. Which is quite flat. I had to walk so much up hill as it was utterly impossible to climb 40 meters.

In the Netherlands quite a lot of people do live in a 50 km radius of their workplace. And 50 km would be a distance you'll travel by train or car. A daily comute of more then one hour in the Netherlands might be considered 'quite a while' but I guess this is different in the USA.

The Netherlands had the opportunity to hit the reset switch in the 1970s with public support, that pushed through the changes in infrastructure and culture to foster a cycling centric society.

I'm wondering if that could ever happen today, I think the motoring/oil and road lobbyists are so well entrenched and organised in governments across the world, I highly doubt it.

I live in London and would never dream of cycling here, I'd be too nervous to do it.

Amazing infrastructure for cycling (at least in Amsterdam).

Its also pan flat, so it is very practical to get anywhere by bike, in the way that San Francisco's hills makes it very impractical.

I wish more cities would push for the infrastructure and culture required for this to work... in my city there are few bike lanes (and not all interconnected, so you have to switch between bike lane and normal traffic lanes) and both cyclists and motorists are equally ignorant of how to behave around each other. (At least in enough quantity to make it a problem)

Having spent a little tiny bit of time in the Netherlands in both Amsterdam and The Hague, I suspect it's simply the combination of a flat landscape combined with comfortable weather for strenuous outdoor activity and most people living in pre-car cities which are sized about right for pedestrian activities which fed into a virtuous cycle that both recognized these things and then built legal and physical infrastructure to support them, which in turn made cycling easier and more convenient and so on.

It's very hard to conveniently cycle around many other cities due to not having one or more of the three foundations needed to kick off the cycle. Even in non-optimal cities, putting a cycling infrastructure in place doesn't necessarily result in lots of cyclists and doesn't necessarily determine cycle usage.

For example, the entire U.S. state of Florida might be an ideal biking location. It's flat after all, but most of the state was built to support cars, and the weather can be mighty hot. It also has the highest cyclist fatality rate in the U.S. with Orlando specifically often called out as one of the worst cities in the world to cycle in.

I've been living and working in The Hague for about 3 months.

Here there are bike paths everywhere (pretty much alongside every road) and they're quite wide. Bikes have their own set of traffic lights.

If you manage to get your hands on a yellow public transport card (ov-chipkaart) then you can even rent a bike from the train station (some train stations have a separate section where they keep the bikes) and it only costs about 3 Euros per day.

I think the superiority of the Netherlands when it comes to cycling is pretty clear, and has been for a long time. What bothers me about this superiority is the perceived need to point it out on a fairly regular basis.

It's very easy to look at one's fortunate circumstances and wonder why others can't replicate them, so why the constant incredulousness around how the Netherlands stands as an example that should be followed?

Perhaps shrinking every nation to the size and geographical structure of the Netherlands would help. Other nations could also raze their suburbs and reconstruct into quaint little villages with great respect for cyclists.

Thanks for asking BBC.

Here are some answers:-The Netherlands are flat.-Bikes only use renewable energy.-Riding a bike is healthy.-There is a lot of supporting infrastructure.-Car drivers are well trained, so that they don't impose as much of a risk as car drivers in other countries.-In stark contrast to other countries especially but not limited to the United States. In the Netherlands everything is reachable by bike. For example but not limited to: Workplace, school, kindergarten, grocery shop, shopping district, cinema.

I did a casual bike tour through hundreds of miles of Netherlands and Belgium. We wore helmets, obviously.

Not wearing a helmet is inconsisent with having many standards for reflectors and traffic planning. Although someone maybe slightly more careful, falling on a bicycle means a risk for head injuries. Why not take reasonable precautions, including instructing people that helmets do not add safety to anything besides head injuries? They're not a panacea, but protect against certain classes of injuries.

Anecdotally: When I was a kid, an obscured oily patch of road contributed to a fall to one side, head first, and slide for about 10 feet and the helmet I was wearing cracked instead of my skull. Road rash but didn't die or end up with traumatic brain injury.

i was in Amsterdam seven years ago for work; the folks at the local shop i was there to do business with asked me to stay on an extra day and they would take me on a tour of Amsterdam.

we decided on a bike tour so we walked to a place where i could rent a bike. Of the 50 or 60 "top bar" (men's) bikes, every one was too big, even if they collapsed the seat post, the frames were still to big. (I'm 175 cm, or 5'9"?) I had to settle for a ladies' step-through.

i cant seem to find any references to the 'no need for a parking place, no need for gas, brings two people at least, police not that much of a hassle when you cycle drunk (and if you really drank too much, you cant cycle...), usually in a city 10x faster due to one-way traffic etc'

And plenty of (serious) accidents happen here too involving cyclist. Though indeed, car drivers are generally in fear of hitting one for legal and insurance reasons.

From having completed the London to Brighton bike ride at the weekend I have a good idea of what really makes the difference and that is having roads closed to motor vehicles. The London to Brighton route is closed to traffic and some of the rural stretches are as wide as a Dutch bike path. Up until now I have believed sharing the roads is how to go but now I know that cycling infrastructure is needed. It is the experience that matters and cycling away from the cars is a totally different thing to dodging traffic. It makes cycling more like walking in a park.

As an aside, I have thought about putting money down for an electric car but then I look at electric bicycles and finally settle for a normal bicycle. I hope more people question why the big box and get a two wheeler powered by a 5kg battery or their own oomph.

Because cars are so extremely expensive here in the Netherlands.

The fact that the bicycle paths here are amazing in most of the country is secondary.

Bicycles are at extreme risk of theft in major cities. There is nothing to romanticize about crappy bicycles. People do not ride garbage old bikes by choice, but out of necessity. People ride garbage on rusty wheels because they have been burned by theft multiple times.

Criminals with trucks in Germany and the Netherlands routinely roll up to train stations and steal dozens of bicycles at a time, take them to get resprayed in Poland, then resell them.

If you chained your bicycle to something in a way that isn't aesthetically pleasing, the government will steal your bicycle and you will have to retrieve it at a cost plus your expensive lock will be destroyed. This assuming you can find your bike.

Don't be fooled into thinking that this is bicycle utopia. You are only less likely to get killed by a car. This is a huge plus. But the rest of the story is bleak.
